Ive had my canon 550D for about a month now and am loving it, starting youtube videos with it, just about to buy a RODE shotgun mic for it to. Along with all the great pictures it can take, and if u understand DSLR's a bit more full manual mode can do amazing things, but i really love that it can record at 24fps which is what most movies are filmed in all at 1080 aswell.

made a few joke vids with my mate to test it out here: http://www.youtube.com/user/cougermoon
(ill make more if ppl like em)

But still have lots of learning to do even after reading all the manuals and a bunch of online guides.

DSLR's are a different world of photo taking

hope this helps

Cheers

Will
